Built with an aluminum oxide abrasive and a vitrified bond, this wheel operates at up to 3600 RPM and delivers coarse-grade material removal at 46 grit. The H hardness code and porous structure help control heat buildup during extended grinding passes. At 7 inches in diameter, 1\/2 inch thick, and bored to 1-1\/4 inches, it mounts directly on standard surface grinder spindles. The ruby-colored 48A specification matrix is a recognized formulation for hard and soft carbon steels as well as tool steels. Licensed grinding wheel technicians and toolroom machinists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for flat surface grinding operations in both production and toolroom settings. The 48A46-HVP2 specification targets hard carbon steels, soft carbon steels, and tool steels. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The Type 1 straight-wheel profile with no recess and no taper fits standard spindle arbor setups common to bench and surface grinding machines found in machine shops and manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent coarse-grade stock removal\u003c\/li\u003e\n\u003cli\u003e46 grit, H hardness (Soft hardness rating) for aggressive yet controlled cutting action on ferrous metals\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure reduces heat accumulation during surface grinding passes\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile with no recess and no taper for straightforward spindle mounting\u003c\/li\u003e\n\u003cli\u003eRuby 48A series formulation rated for hard carbon steels, soft carbon steels, and tool steels\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before mounting or removing wheels. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated 3600 RPM maximum speed. Flanges, blotters, and arbor nuts must be properly matched to the 1-1\/4-inch bore per ANSI B11.9 grinding machine safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 48A46-HVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252916215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541598470450,"sku":"66252916215","price":89.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6aed3c1138c37109896c7d3aa842243.jpg?v=1785880333","url":"https:\/\/voomisupply.com\/products\/norton-66252916215-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
